V.Lettera Patent No. 68,664, dated September 10, 1867.

llnrnovnn MATERIAL-ron rtoons or nltrfmns.

Be it known that I, REINHARD Srnrnnl., of the city of New York,` have invented a` new and improved Material for Bottoms or G ratings of Malt-Kilns; and I dol hereby declare the following to be an exact descrip-` tion of my said invention. p

The nature of my invention consists in 4obdurating and stiiieningwire cloth, and to render it strong and its surface smooth, and then to attach such wire cloth as bottoms orr gratings to malt-kilns.

To enable others skilled in` the art to which my invention relates to makeand use the'same, I will proceed v to describe the same, reference being had to the annexed drawings,` in which-f- Figure 1 represents a plane view of the new material, and

Figure 2 a sectional view thereof. p

I deem it proper tostate'that"heretofore the gratings o r bottoms for malt-kilns were made of sheet-iron plates, in which small conical holes were drilled, through which the hot air passed. In order 'to prevent the malt from falling through these holes in the bottom their size had to he very small, and the number of the holes could not he large, as the close contiguity ofthe holes would -havempaired the strength 4ot' the plate. Owingto 4these circumstances the great body of the malt could not readily come injdirect contact with the hot air, (emanating from below the bottom,) the malt had to be constantlystirred, and therefore the process of malt-drying was protracted and inconvenient. Y l

The application offiny invention obviates the'ahove defects. .A grating orbottom made of wire-cloth rolledor pressed as hereinafter described admits'the lintrusion of hot airto an unlimited extent, the holes `'are close: to each other, and very numerous, and the resistibility or strength of this material is superior toithat of the perforated sheet iron at present used. The surface of this wire cloth is smooth, otherwise-it would present impedi` ments to the shovelling and stirring of the malt. A

The'wire cloth is Woven in the usual manner, and the sizeof the wire threads 'may -vary according tothe' Vdesiredstrength of the bottoms or gratings. Iron, copper, or any other suitable Wire may be used. When thc nire is woven into cloth the cloth is rolled or pressed between two cylinders, and then the material isready for use.- It may, however, (if of iron wre,) before or after being pressed, be, galvanized.` It is then appliedto the. malt-kiln in the same manner in which the .gratings now in useare applied. The substitution of this material for the iron plates secures the advantages above enumerated.

What I claim as my invention, and 4desire to secure by Letters Patent of the United States, is-

1. The pressingand rolling of'wire cloth, in the manner and for the purpose described. u p 2. The application of rolled or pressed wire cloth as a bottom to malt-kilns, inthe' manner` and forthe pur-` pose described.
